摘要
结合岩溶地基处理的工程实例,利用有限元法对天然地基及水泥土搅拌桩复合地基、CFG桩复合地基、CM三维高强复合地基三种加固方案进行数值模拟,揭示了三种方案加固岩溶地基的变形特性及应力分布。
Combined with engineering examples of karst foundation treatment,three reinforcement programs for natural foundation and cement mixing pile composite foundation,CFG pile composite foundation,CM three-dimensional high-strength composite foundation are numerically simulated using finite element method.Deformation characteristics and stress distribution of karst foundation reinforced with these three programs are disclosed.
